Equetions Flashcards
What is the overall equation for photosynthesis?
Sun + CO2 + chloroplast → energy + glucose + oxygen
What is the primary purpose of photosynthesis?
To convert light energy into chemical energy in the form of glucose.
What are the reactants of cellular respiration?
Glucose and oxygen.
What is the overall equation for cellular respiration?
Glucose + oxygen → CO2 + water (H2O) + energy and heat
True or False: Photosynthesis occurs in the mitochondria of plant cells.
False
Fill in the blank: The main pigment involved in photosynthesis is _____ .
chlorophyll
Which process occurs in the chloroplasts?
Photosynthesis
What is produced as a byproduct of photosynthesis?
Oxygen
True or False: Cellular respiration can occur without oxygen.
True
What is the process called when glucose is broken down without oxygen?
Anaerobic respiration
Which type of cells perform cellular respiration?
All cells
What are the two main stages of photosynthesis?
Light-dependent reactions and the Calvin cycle.
What is the main energy currency produced during cellular respiration?
ATP
Fill in the blank: The Calvin cycle occurs in the _____ of the chloroplast.
stroma
Which gas is taken in by plants during photosynthesis?
Carbon dioxide
What is the relationship between photosynthesis and cellular respiration?
Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy.
True or False: The primary source of energy for photosynthesis is heat.
False
What do plants convert light energy into during photosynthesis?
Chemical energy
In which organelle does cellular respiration primarily occur?
Mitochondria
What type of respiration occurs in yeast and some bacteria?
Fermentation
Fill in the blank: The process of converting glucose into energy is called _____ .
cellular respiration
What is the main purpose of the light-dependent reactions?
To capture and convert solar energy into chemical energy (ATP and NADPH).
Which molecule is regenerated in the Calvin cycle?
RuBP (ribulose bisphosphate)
What is the role of NADPH in photosynthesis?
It serves as a reducing agent in the Calvin cycle.
True or False: All living organisms perform cellular respiration.
True
What is the main difference between aerobic and anaerobic respiration?
Aerobic respiration requires oxygen, while anaerobic respiration does not.
